Claas 7030 wont release 3rd service pressure

[Morgans23]

Any thoughts why our claas 7030 won't release pressure on 3rd service, finding it a right pain trying to attach grabs etc and also getting covered in oil each time. Many thanks

By right hand rear wheel chech of the little accumilator has gas in. That supplies pressure to servos with engine off. Will boom lower when you push buttons to de pressure

OK will check this thank you. What will happen when I take it out? Boom suspension doesn't work either,anything related?

 

[lexion780tt]

Could be electrical or the big accumilator has gone as well. If you hear a gas escaping should be OK if not much gas and oil come out accumilator has failed.

The bigger one of the 2 by rear right wheel is boom suspension dose the orange light come on in the cab for it?

 

[Morgans23]

Yes orange light comes on. Checked both accumalators today and just frothy oil came out. Would you have and part numbers ?
